TIRE-TOOL.

Specification of Letters' Patent.

Patented Apr. 15, 1913.

Application led March 12, 1912. Serial No. 683,365.

T 0 all 'whom t may concern.'

Be itknown that I, CHARLES S. EDWARDS, residing at Prineville, in thecounty of Crook and State of Oregon, have invented a new and ImprovedTire-Tool, of which the following is a specification.

This invention relates to that class of tools more especially designedfor applying or removing automobile tires, and it primarily has for itsobject 'to provide a tool of the character noted of a simple andeconomical construction that is easily operable 4and efficient for itsintended purposes.

' Another object of this invention is to provide a tiretool which whilecapable of use in connection with the ordinary run of tires is moreparticularly adapted for the re-,

moval andy application of Dunlop or mechanically fastened tires andwhich is also useful for taking off and putting on the tire retaininrings.

With furt er objects in view that will be' hereinafter apparent thisinvention consists of a tire tool embodying the peculiar and novelfeatures of construction hereinafter fully explained, specificallypointed out in the appended claims and illustrated in the accompanyingdrawings, in which:

Figure l, is a side elevation of the tool, the ysame being shown appliedto the wheel and in a normal position. Fig. 2, is a similar view,showing the sliding or pusher device set for forcing the retaining ringand the adjacent tire edge away from` the clencher member of the rim,the tool being shown at its lever shifted position for prying in theretaining ring, in dotted lines. Fig. 3, is a detail view, in sideelevation, showing the tool set for pushing the tire off the rim of thewheel, the tire and wheel rim being shown in section. Fig. 4, is a planview of the tool, the vehicle spoke being -in section, Fig. 5, is a sideview of the tool, showing the sliding or pusher device set for forcingthe tire off the rim of the wheel, the tool being Shownat itslevershifted position for pushing the tire oil', in dotted lines. Fig. 6, isa perspective view of the several parts that constltute the tool, separated fromv each other. Fig. 7, is a longi tudinal section of the screwfeed portions thereof. Fig. 8, is a cross section of the same on theline 7-7 on Fig.7. l

In carrying out my invention, I furnish a tool consisting of a member1in the nature .of a flat bar, the opposite edges ofwhich form guides10. At the outer end member 1 has a vertical fiange 11, apertured at 12for the passage of the shank 20 of a feed screw -2, which also carries acollar 22, located on the inside of the flange 11, through which theshank 20 passes.

25 is a crank handle on shank 20.

The-member 1 also has an integral pendant armor bracket 13, the lowerend 14 of which is bifurcat-ed and apertured to receive the inner end ofa .spoke gripping member 3, pivotally mounted in the said end 14 andheld to an upper or`normal position relatively to the member 1, by acoiled spring 4 joined at theends to the bracket 13 and the grippingmember 3, the latter having a stop-Shoulder 31 for engaging the bracket,as shown. The outer end of member 3 terminates in a hook 32 for slippingover the wheel spokes and it has a yielding covering 33 to avoid marringthe spokes when applied.

5designates a pusher device or member that comprises a tubular body 50having at the rear end a solidnut portion 'that is internallythreadedfor receiving the screw 42, as is best shown in' Fig. 6, and at the saidend the member 5 has pendant hook-like flanges 51 for sliding on theguideslO of the stationarymember 1, see Flgs. 1 and 7.

-The pusher 5 has a head member 52 at the inner end for engaging thetire and the said head includes downwardly and forwardly projecting ends53. The ends 53 have transverse grooves 54'for engaging the de tachablefiange and a curved seat 56 for engaging the tire.

6 designates the ordinary tire tube, 7 the detachable ianges,` 8 thewheel rim, and 9 the locking ring, and 90 the' wheel spoke.

From the foregoingv taken in connection with the drawings it is believedthev constructions and the general manner of its use and the advantagesof my invention will be readily apparent to those skilled in the art towhich 1tl appertains.

In view of the eculiar construction and arran ement of tiie parts shownand describe in applying the tool, it is only necessar to hook themember 3 around the s oke an apply the head 52 against one o` thedetacha le flanges 7 as indicated in full lines in Fig. 2 of thedrawings. The tool is then swung u to the position shown in dotted linesin *ig 2, which forces the tire and iange inwardly away from the lockingring 9 at the corresponding side, and the locking ring 9 is removed. Thetool is then detached from the wheel, and the flange 7 at the side fromwhich'the locking ring has been removed is slipped 0E the rim 8, afterwhich, the tool is applied to the opposite side of the wheel asindicated in Fig..3, with the head 52 in engagement with thecorresponding side of Ythe tire. By then turning the crank to operatethe feed screw 2, the tire can be readily turned ofi" the rim.

After having partially pushed off the tire at one point, the sameoperation is repeated by attaching the tool to another nearby spoke landagain repeating all the way around the tire. After thus having initiallypried off (or on) the tire, the pusher member is fed farther forwardlyto force the tire off farther and the prying operation is repeated asbefore.

While I prefer to arrange the several parts that constitute the tool inthe manner shown and described, I do not purpose to conine myself to thesaid exact arrangement, since these may be readilyvaried or modified andbe within the spirit and the scope of the appended claims.

For example, the coiled spring for holding up the hook 3, need not beexposed, but may be incased in any well known manner, again in place ofthe fiat guide plate, the said part could be made tubular and thesliding or pusher member made to reciprocate within the tubular part andheld from turning by the well-known groove and spline connection. Againin place of the crank'handle 25 a wheel could be used for turning thescrew.
